DNS

Port: 53

Domain Name System (DNS) is the hierarchical and distributed naming system used to identify computers reachable through the Internet. These are most commonly used to map human-friendly domain names to the numerical IP addresses computers need to locate services.

Any Information

dig ANY @dns_ip domain

Information

dig TXT @dns_ip domain

Tranfert Zone

dig axfr @dns_ip domain

Reverse Lookup

dig -x ip @dns_ip

Reverse All Address

dnsrecon -r 127.0.0.0/24 -n ip_dns

SNMP

Port: 161 / 162

SNMP is used to monitor the network, detect network faults, and sometimes even used to configure remote devices.

List devices

snmp-check ip

RPCBind

The rpcbind utility maps RPC services to the ports on which they listen. RPC processes notify rpcbind when they start, registering the ports they are listening on and the RPC program numbers they expect to serve. - redhat

Port: 111

Info

rpcinfo -p ip

NFS

A Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. - redhat

Port: 2049

To bypass permission change your uid

Show NFS

showmount -e squashed.htb

Mount

mount -t nfs squashed.htb:/ nsf_mount -o nolock

Scan Local Network

ARP Scannner Tools shows every active IPv4 device on your Subnet. Since ARP is non-routable, this type of scanner only works on the local LAN.

Address Resolution Protocol (ARP) is the Dynamic mapping technique used to map the logical address (IP) to a physical address (MAC).

Arp

sudo arp
Address                  HWtype  HWaddress           Flags Mask            Iface
NameHost                 ether   xx:xx:xx:xx:xx:xx   C                     INTRFC

Netdiscover

Arp-scan

arp-scan -l

List opened port localy

SS

ss -lntu

Netstat

netstat -tulpn

Hydra

Proxy

export HYDRA_PROXY=connect://localhost:8080

Basic HTTP Auth

Post HTTP Login

hydra -l admin -P wordlist.txt -f ip -s port http-post-form "/login.php:username=^USER^&password=^PASS^:F=<form name='login'"

SSH

hydra -L user.txt -P pass.txt -u -f -t 4 ssh://ip:port
